Fix language display for ISO 639-2-only codes (e.g. mul, und)

2026-04-08T17:38:24Z

LoadCultures() in LocalizationManager skipped all iso6392.txt entries without a two-letter ISO 639-1 code, dropping 302 of 496 languages including mul (Multiple languages), und (Undetermined), mis (Uncoded languages), zxx, and many real languages like Achinese, Akkadian, etc. This caused FindLanguageInfo() to return null for these codes, which meant: - ExternalPathParser could not recognize them as valid language codes in subtitle filenames, so the Language field was never set - DisplayTitle fell back to the raw code string (e.g. "Mul") Fix by allowing entries without two-letter codes to be loaded with an empty TwoLetterISOLanguageName. Also set LocalizedLanguage in ProbeResultNormalizer for ffprobe-detected streams (the DB repository path was already handled on master).

Only set IsAvc for video streams

Also enables nullable for MediaStreamInfo Makes more properties nullable that aren't always present

Fix zh-CN subtitle language display

2026-01-05T11:22:44Z

The DisplayTitle property was using .NET's CultureInfo.GetCultures(NeutralCultures) to resolve language display names. Since zh-CN is a specific culture (not neutral), it would fall back to the base 'zh' code, resulting in generic 'Chinese' instead of 'Chinese (Simplified)'. This change adds a LocalizedLanguage property to MediaStream that gets populated via LocalizationManager.FindLanguageInfo() when streams are retrieved from the database. This leverages Jellyfin's existing iso6392.txt mappings which correctly map zh-CN to 'Chinese (Simplified)'. The same pattern is already used for other localized strings like LocalizedDefault and LocalizedExternal.

Translate the ISO-639-2/B codes to ISO-639-2/T. (#13068)

2025-04-08T03:29:12Z

* Translate the ISO-639-2/B codes to ISO-639-2/T. This enables 19 additional languages to be displayed correctly. * Convert the 2-dimensional array to a dictionary * Added the French language to the list of ISO-639-2/B codes * Don't change the property, use a local variable instead. * When creating the MediaStream in the MediaStreamRepository ensure that the ISO 639-2/T (f.e. deu) code is used for the language as that is the one the .NET culture info knows. The other code is most likely the ISO 639-2/B code (f.e. ger) which is unknown to the .NET culture info and will result in just displaying the code instead of the display name. * Move the substitution of ISO 639-2/B to /T to the localization manager. Some language (like Chinese) have multiple entries in the iso6392.txt file (f.e. zho|chi|zh|..., zho|chi|zh-tw|...) but the conversation between /T and /B is the same so use .TryAdd. * Change the method definition from GetISO6392TFromB to TryGetISO6392TFromB and return true if a case was found. * Add unit tests for TryGetISO6392TFromB.
